Linux always differentiates between upper and lower case. The two files MyFile.txt and myfile.txt are different file.
Special characters
Do not use special characters except for minus (-) and underline (_) for filenames or directory-names. Don't use the space-character. Use the characters A-Z, a-z, 0-9, -, _ only.
How to move files with ROX
If you left-click on a file and pull it to another directory the file is copied.
You can create your own Puppy-Linux with the following program.
Start the program "Menu | Setup | Remaster Puppy live-CD":
Click on the OK-button.
Choose the partition, on which a temporary working directory should be made with the tabulator-keys.
You should encrypt very sensitive files with the program bcrypt. Bcrypt uses the secure Blowfish-algorithm.
Open a shell and enter:
bcrypt /MyDirectory/MyFile
Then you are asked a passwort (at least eight characters long; you can abort bcrypt with "Ctrl" + "C"). Bcrypt encrypts your file and appends the extension bfe to the file. The original file is deleted automatically.
If you want to encrypt more than one file or a complete directory you should create an archive-file. Start the program "Menu | Utilities | Xarchive archiver".
For further improvement of your security you should store a checksum (a fingerprint) for all files. At regular intervals, but in any case before a backup, you examine the checksums of your files. If the checksums do not agree, the file was changed or deleted.
In order to compute and store the checksums, you open a shell and enter the following commands:
